The first thing I wanted to note is the volatility of the instant messenger mart. I use an app. And there's the elephant in the room: Facebook Messenger

AOL's messenger service - it may not look like it but that's the first one listed - is an ominous declaration 

Heads Up!

AOL Instant Messenger will be discontinued on December 15, 2017.

while eBuddy has given up

A step towards the future: eBuddy Chat is no longer available

Recognizing the decline of the instant messaging networks that eBuddy Chat supports and the rise of smartphone messaging, we have decided to solely focus on making XMS the best smartphone communications tool in the market.
We would like to thank you for being part of the eBuddy Chat journey and welcome you to continue your messaging journey with us on XMS.
